What are the advantages of GoToMyHMI over
Virtual Network Client (VNC)?

VNC stands for Virtual Network Computing. According to its
creators it was conceived as an ultra-thin client system based
on a simple display protocol that is platform-independent. The
RFB (Remote Frame Buffer) protocol in VNC may be implemented at
different levels of complexity. Regardless of the level of
complexity of the underlying display protocol VNC is a
client-server setup that requires installation of the server
software on the HMI-Server end and the client software on the
browser end. (The client software may be a Java-capable
browser.)

VNC clients require an inbound connection to the VNC server for
remote access. This would entail firewall configuration to
permit such an inbound connection or a VPN (Virtual Private
Network) setup. GoToMyHMI Cloud Nodes do NOT require any inbound
connection, so firewall configuration to accept inbound
connection to the HMI-Server behind the firewall is not
required.

GoToMyHMI is our HMI-gateway in the cloud. In the context of
‘HMI in the Cloud’, GoToMyHMI vs. VNC, there’s NO comparison!

Do I need to download any client software or plug-ins to access my HMI?

No downloads, no tedious installs, no plug-ins. Use any standard browser on any device to access your HMI.
Login and you have the HMI in your hands wherever you are: factory cafeteria, or parking lot, or on the beach,
or even the golf course!
